To maintain [[Plausible Deniability]] and hide from magical TV [[Spy Satellites]], any sufficiently powerful or advanced covert organization of heroes, villains, conspirators, or military personnel needs an '''Elaborate Underground Base''' to use as their headquarters and hide their [[Applied Phlebotinum]]. [[After the End]], or in preparation for [[The End of the World as We Know It]], openly known organizations may elect to move [[Beneath the Earth]] as well. And it's a good location for a [[Supervillain Lair]].
Line 14 ⟶ 15:
 
Compare with [[Underwater Base]], [[Island Base]], [[Airborne Aircraft Carrier]] and [[Space Base]]. See [[Beneath the Earth]] for a related phenomenon, minus the [[Applied Phlebotinum]]. May induce [[Sigil Spam]] if the organization really loves their logo.
{{examples}}
 
{{examples|suf=s}}
== Anime and Manga ==
 
* ''[[Neon Genesis Evangelion]]'' has NERV setting up shop inside the GeoFront, a massive cavern that is actually just the upper 11% of an even larger spherical cave almost completely filled up with earth and rock debris. And going [[Up to Eleven]], Terminal Dogma is an Elaborate Underground Base built below another Elaborate Underground Base.
** Not really. Terminal Dogma is a more-or-less natural cavern system. Well, as natural as caves inside a spherical asteroid carrying an alien terraforming device can get.
Line 33:
 
== Comic Books ==
 
* The Batcave from the various ''[[Batman]]'' series.
* The original headquarters of the [[Justice League]] was an elaborate base built into the base of a mountain. Several other teams have taken this base out of mothballs, such as [[Young Justice (comics)|Young Justice]].
Line 50 ⟶ 49:
* In the ''[[Zorro]]'' comics written by Don McGregor (for Topps and Dynamite), Zorro has an elaborate underground base that rivals the Batcave.
 
== Fan Film Works ==
* Expressed, averted and [[Played for Laughs]] at various points in ''[[The Secret Return of Alex Mack]]'':
** Played painfully straight by various bad-guy headquarters, most especially the complexes under the Spencer mansion and the Umbrella building during the ''[[Resident Evil]]'' segment. Lampshaded and mocked by both Jack O'Neill and Alex.
** Averted in that the SRI operates out of several perfectly above-ground military bases and office blocks.
** [[Played for Laughs]] with the backdrop Alex literally cut-and-pastes together for use in videoconferencing as her superhero identity Terawatt, which shows a huge Batcave-like base that most of the SRI knows doesn't really exist.
 
== Film ==
* ''[[THX 1138]]''
* ''[[Logan's Run]]''
Line 60 ⟶ 64:
* ''[[The Avengers (1998 film)|The Avengers 1998]]''. Sir August's underground base, which is on an island in the Thames in London.
* ''[[James Bond (film)|James Bond]]'', amazingly enough, has very few of these, despite the series being ridden with cartoon villans and conspirators. The closest they ever got were the hollowed-out volcano complex in ''[[You Only Live Twice]]'' and Drax's Amazon launch facility in ''[[Moonraker]]''.
** ''[[GoldeneyeGoldenEye (film)|GoldenEye]]'' had an elaborate underground military bunker at Severnaya, and the [[Big Bad]]'s Lair is actually below the giant pool where the cradle antenna is hidden.
** ''[[Dr. No]]'' had an elaborate nuclear facility but it's not clear that it was underground. Although fairly likely, given that it explicitly is in the book and in the film they dine in a glass-windowed room below the waterline and thus presumably underground as well.
* In ''[[Hellboy (film)|Hellboy]]'', Rasputin has an underground lair {{spoiler|located under his mausoleum in Moscow}}
Line 75 ⟶ 79:
* The Wildfire facility in ''[[The Andromeda Strain]]''. The only entrance is the elevator shed, and the facility topside ''is'' what it's disguised as - a wheat modifying facility.
* Willy Wonka's crazy factory in ''[[Charlie and the Chocolate Factory]]'' is mostly underground. The book contains an explicit explanation of this by Wonka, where he tells everyone that he decided to expand his factory by tunnelling downward and outward so that he could basically expand indefinitely without ever having to buy any more land or pay any rent to the property owners most of his factory is under. This would, of course, be all kinds of illegal in real life, but Wonka doesn't care.
* A similar rationale obtains for the enormous set of underground tunnels built by the deep-down dwarfs in Ankh-Morpork in [[Terry Pratchett]]'s ''[[Discworld]]'' novels. By digging under the city, they can create their own dwarfs-only authentic dwarf mine under the city, unbeholden to city law or city rents. After the events of the book ''[[Thud!]]'', the deep-downers are thoroughly discredited and Lord Vetinari appropriates their delve for the city government. (It is heavily implied that these tunnels will form the basis of a future Ankh-Morpork subway system.)
** And the dwarfs have better legal standing than Wonka, considering that on parts of the Disc that dwarfs normally live, such as the Ramtops and Überwald, dwarf-law does cover the underground and is entirely separate from surface law. This just isn't true on the Sto Plains.
 
** The bulk of Dwarf civilization away from AnkAnkh-Morpork is also mostly underground. There are huge cities.

The bulk of Dwarf civilization away from Ank-Morpork is also mostly underground. There are huge cities.
* Supervillain Doctor Impossible of ''[[Soon I Will Be Invincible]]'' has a base descending deep into the Earth: when he returns to it after his last defeat, the deeper levels are still intact. Also, his first base was dug down from the basement of an ordinary suburban house.
* [[Super-Hero School]] Whateley Academy in the [[Whateley Universe]] has ''extensive'' underground stuff. Powers testing, deviser workshops, arenas, you name it. And that doesn't even cover the highly dangerous sewer system there. Lampshaded by mentions that they now have to be quite careful where and how much they dig, in order to avoid having the above-ground structures fall into a sinkhole.
Line 85 ⟶ 87:
* Salamandastron for the Long Patrol, and the Kingdom of Malkariss for one set of baddies, in the ''[[Redwall]]'' books.
* Tolkien was big on these, both for good and bad guys. In ''[[The Hobbit]]'', you have dwarf fortress in the Lonely Mountain (owned by Smaug the dragon). In ''[[The Lord of the Rings]]'' you have Moria, also mostly dwarven but built with some assistance from the high elves. Melkor, the [[Big Bad]] of ''[[The Silmarillion]]'' had [[Hell|Utumno]], which amounted to an underground ''country'' and Angband (whose excavation produced enough refuse and slag to pile into ''three'' 10 km high mountains), and (somewhat unusually) ''elven'' underground fortresses in the form of Nargothrond (built with some assistance from the dwarves, pwned by Glaurung the dragon) and Menegroth (also built with dwarven help).
** The Hobbit mentioned a few elven cultures, one of which was the "deep elves," which might refer to the Noldor who lived in places like Nargothrond (though canonically, the underground-dwelling Wood Elves of Mirkwood are separate from the Noldor). Underground elves are rather unusual... perhaps the assumption that [[Our Elves Are Better]] means they don't live in holes in the ground anymore. Only [[Exclusively Evil|dark elves]] would do that sort of thing nowadays.
 
** While, contrary to [[Our Elves Are Better|tradition]], Elves of all kinds (Noldor and Sindar- see Menegroth or Thranduil's halls) do live underground in Tolkien's books, it's fair to assume that "deep-elves" in that case, as in the ''Lost tales'', refers to "Gnomes", or Noldor, Elves which are deep in knowledge and thought, not Elves who dwell underground.

** The Dead Men of Dunharrow lived in an elaborate system of caves in the mountains. Even 3,000 years after they died.

* The Alchemists' Guild in ''[[A Song of Ice and Fire]]'' has an elaborate underground Guildhall composed of a labyrinth of tunnels, cells, halls, and warehouses filled with highly explosive wildfire. The place is designed to limit the damage should a cache of wildfire combust.
* [[Stephenie Meyer]]'s ''[[The Host (novel)|The Host]]''
Line 105 ⟶ 104:
* The Observatory in ''[[Septimus Heap]]'' is heavily hinted at to be this.
 
== Live -Action TV ==
 
* Gerry Anderson seems quite fond of this one.:

** In ''[[Joe 90]]'' the BIG RAT was located in a secret underground facility beneath Professor McClaine's house.
 
** In ''[[Stingray (1964 TV series)|Stingray]]'', during alerts the entire ''city'' of Marineville can descend into a secure underground facility on hydraulic jacks. (Just in case anyone thought ''[[Neon Genesis Evangelion]]'' did that first...)

** SHADO Headquarters in ''[[UFO]]'' is located beneath a film studio. Think about it...

== Tabletop Games ==
* Alpha Complex from ''[[Paranoia (game)|Paranoia]]'' is usually an elaborate underground warren with all the super-science facilities you could ever need.<ref>Then again, continuity has never been a big deal in ''[[Paranoia]]'' so it can be a a domed city, underwater, whatever the GM desires.</ref>

* The dwarves of ''[[Warhammer Fantasy Battle]]'' live in huge undergound cities, following the example set by [[J. R. R. Tolkien|JRR Tolkien]]. And the [[Rodents of Unusual Size|Skaven]] live below those in big cities and tunnels that span every continent.
* ''[[Warhammer 4000040,000]]'' gives us the planet of Calth in the Ultramar sector, where this is the ''only'' kind of base because the sun is deadly. Necron tomb complexes also qualify.
* Despite the name, virtually none of the "dungeons" in any ''Dungeons & Dragons'' campaign are prisons. They're either natural caverns full of unintelligent monsters (rare), tombs full of undead (uncommon), or this trope for the [[Villain of the Week]] (''extremely'' common).
** Taking this to its logical extreme is [http://images.yuku.com/image/pjpeg/45536ba641a897edcc85536f05a293fe97906a7c.jpg Malsheem], fortress of [[Satan|Asmodeus]], [[God of Evil|god of sin and tyranny]] and [[Demon Lords and Archdevils|lord of devils]]. As the fourth edition has transformed the Nine Hells into a planet, Asmodeus' fortress is comprised of the ''entire core'' of that planet.

As the fourth edition has transformed the Nine Hells into a planet, Asmodeus' fortress is comprised of the ''entire core'' of that planet.
* The entire raison d'etre of House Telamones, Nosferatu bloodline from [[Vampire: The Requiem]]. They build elaborate underground bases to suit the tastes of their undead betters, but woe to the Would-Be Vampire Overlord who accepts the bid from a competing firm... it's mentioned in the text that House Telamones has BLOWN UP an entire CITY BLOCK OF SEATTLE rather than lose a bid.
 
 
== Theater ==
 
* The prototypical Elaborate Underground Base may well be Erik's lair under the Paris Opera in the various incarnations of ''[[The Phantom of the Opera]]'', making this [[Older Than Radio]].
 
== Video Games ==
* The whole of ''[[Breath of Fire|Breath of Fire V]]'' takes place in a geofront like super cave.
 
* The whole of Breath of Fire V takes place in a geofront like super cave.
 
* A few games have appeared where constructing an Elaborate Underground Base is a major aspect of the gameplay, notably:
** The ''[[Dungeon Keeper]]'' series
Line 169 ⟶ 160:
** ''[[Minecraft]]''
* ''[[BioShock (series)]]'' takes place in a ''underwater'' city/base named Rapture, where Applied Phlebotinum is developed, refined, and horribly goes wrong - the player's stated goal is to get out alive.
* ''[[City of Heroes]]'' features this to an almost ridiculous extent. The Cobra-wannabe Council (formerly the Fifth Column) generally base themselves in converted caves, as do the [[Alien Invasion|Rikti]], and even the evil cultist Circle of Thorns have their ancient underground city. The Faultline zone (former [[Scrappy Level]] [[Rescued Fromfrom the Scrappy Heap]]) is said to be filled with former superhero bases that were abandoned in the earthquake that gave the zone its name, and people are trying to dig them up...

** Not to mention the Shadow Shard - an alternate dimension seemingly comprised entirely of floating islands in the sky, with caves and bases dug into them anyway. If the game world had a consistent geometry, it'd likely resemble a very big ant hill with more empty space than rock.
* ''[[Pokémon Red and Blue]]'' and ''[[Pokémon Gold and Silver|Gold and Silver]]'' and their remakes have the Team Rocket bases, which is actually pretty elaborate considering they tend to build them under game corners and converted ninja bases.
Line 182 ⟶ 172:
** ''Fallout 2'' had the Sierra Army Depot and the Hubologist base. The Brotherhood bunkers in the Den, NCR and San Francisco might also count.
** ''Fallout 3'' had Raven Rock and the Rockland comm. facility.
** ''Fallout 4'' had The Institute, an underground base serving as the HQ of the organization of the same name, and the only way to enter or exit is by teleporting (“relaying”).
** ''Fallout Tactics'' had the Brotherhood bunkers and Vault 0 which was simply the Cheyenne Mountain Complex coverted into an even larger facility.
* ''[[First Encounter Assault Recon|F.E.A.R.]]'s'' Armacham Technology Corporation established the main facility for the Origin Project in an old military-industrial complex, and built the entire facility deep underground. Emphasis placed on the past tense, what with the [[Earthshattering Kaboom|explosive ending]] of the first game.
Line 220 ⟶ 211:
* The Descent series lives for this trope. Granted, a lot of them are mines, but there are a bunch of military, scientific, and testing facilities as well. Of particular note is the final level of Descent 3, Dravis' Stronghold.
* In ''[[Metal Gear]] 1'' and ''[[Metal Gear Solid]]'', the titular [[Humongous Mecha]] is hidden in one of these.
** ''[[Metal Gear 2: Solid Snake]]'' has a variation: Although Metal Gear D is fought in the third (sixth?) basement floor of the main building of Zanzibar Land's detention center, it is not specified if it was actually the main hangar for Metal Gear D. Similarly, the Big Shell is technically above ground (or in this case, above water), but it is disguised so well as a cleanup facility that the personnel could literally get away with having armed forces stationed there as well as developing Arsenal Gear without the populace ever suspecting anything.
*** This seems to be fusing metal gear two, and metal gear solid two.
** In ''[[Metal Gear Solid: Portable Ops]]'', there are three elaborate underground bases: One is the Nuclear Storage Facility (which is the deepest mapped area of the game), another is the Silo Complex (which is pretty deep underground, although the mapped areas themselves are actually shallower than the Nuclear Storage Facility), and it was originally intended in-game to have more than one missile silo. The last one isn't actually visited by the Player: {{spoiler|It is the underground bunker underneath Langley that the CIA director attempted to retreat under with the impending nuclear strike against America with his half of the Legacy, and where Ocelot essentially murdered him and made it look like he committed suicide.}}
** In ''[[Metal Gear Solid Peace Walker]]'', both the heroes and the villains have elaborate bases: The Peace Sentinels had an AI Weapon assembly plant situated within a pumped storage hydroelectric power plant within Irazu's crater, an AI programming lab constructed either within an unknown ruin or an AI lab disguised as a ruin (Paz's description of the plant makes the ruin's exact origin a bit ambiguous), and an AI Weapons forwarding/Peace Walker construction base built within a gold quarry. In addition, the FSLN / KGB's drug facilities were also disguised as Banana and Coffee processing factories, and the Militaires Sans Frontieres also utilized an elaborate base in the form of an off-shore OTEC research facility.
* The Ancients in (old verse) [[Might and Magic]] seems to have been fond of placing large facilities underground. The inhabitants of Deyja went one step beyond and built themselves an Elaborate Underground ''City''.
 
 
== Web Comics ==
 
* In ''[[Narbonic]]'', Narbonics Labs moved to an underground lair early in the strip's run. Later subverted when Madblood brags to Helen about ''his'' underground lair; when she and Mell come to visit, they find him [[Basement Dweller|living in his mother's basement]].
* Seems to be the basic design for all Orsintos laboratories in ''[[Sluggy Freelance]]''. Surprisingly, there's been nothing so far to suggest that [[Omniscient Council of Vagueness|Hereti-Corp]] has one of these.
Line 236 ⟶ 225:
 
== Web Original ==
 
* In the ''[[Global Guardians PBEM Universe]]'', most of the [[Diabolical Mastermind|Evil Overlords]] and [[Evil Overlord|Diabolical Masterminds]] have one of these. The most notable example might be [[Nebulous Evil Organization|TAROT's]] primary base in the United States. It is a multi-level complex located four stories beneath the Pentagon's lowest level, and is entered through a secret elevator located in that building. The fact that Federal law enforcement agencies would never think to tear the Pentagon apart looking for it amuses The Emperor greatly.
* Pelvanida from ''[[Darwin's Soldiers]]'' is an underground military research base. It is not really "hidden" per se, though as quite a bit of above ground infrastructure is present.
 
== Western Animation ==
 
* In a series full of [[Supervillain Lair]]s to begin with, in the ''Birdman'' episode ("Number One") that brought them into the open and really defined them as a threat, [[Nebulous Evil Organisation|F.E.A.R.]] turned out to have an elaborate underground base.
* In the ''[[Chip 'n Dale Rescue Rangers (animation)|Chip 'n Dale Rescue Rangers]]'' pilot, Aldrin Klordane had turned a cave conveniently placed underneath the Federal Gold Reserve into his own Elaborate Underground Base which not only has a diagonal monorail, but even a real railroad connection.

* Underground command-and-control centers started getting popular sometime after [[World War I]], and much more so after nuclear weapons and ICBMs. [https://web.archive.org/web/20150903044739/http://www.greenbrier.com/site/bunker.aspx Greenbrier Resort] was the site of a US Congressional command center for 30 years, until [http://www.washingtonpost.com/wp-srv/local/daily/july/25/brier1.htm a Washington Post reporter exposed its existence in 1992.] Cheyenne Mountain, Colorado, is quite famous as the "brain" of [[wikipedia:NORAD|NORAD]] (NORth-american Air Defense), SAC (Strategic Air Command, bombers and land-based ICBMs) and the US Space Command (more to do with satellites, though). The latter two are now defunct, absorbed into other organisations. NORAD is now based at Peterson Air Force Base (a conventional above-ground air force base nearby), but keeps Cheyenne Mountain on warm standby.

** The famous [[wikipedia:White House Situation Room|Situation Room]] (yes, it really does exist) underneath the West Wing of the White House. Yes, this is where the President and his cabinet meet to make life-or-death decisions. No, it is not full of beeping computers.
** Russia, ex-Soviet Union, undoubtedly has its own, but locations are disputed.
*** There's supposedly an entire [[wikipedia:Moscow Metro -2|secret subway system under Moscow]], ''bigger'' than the regular one and buried up to 200m underground, linking numerous important buildings and providing means for movement and evacuation of VIPs.
*** Nobody in the West seems to know what's under [[wikipedia:Mount Yamantau|Mount Yamantau]], but whatever it is, it's definitely '''huge'''.
** Similar to the Greenbrier Resort are the Canadian [[wikipedia:Diefenbunker|Diefenbunkers]]
** A few shots in the movie ''[[War GamesWarGames]]'' showed the actual Cheyenne Mountain complex. The NORAD room in that was a mock-up (the most expensive movie set ever at that time) and far more snazzy than the real one.
*** The Second-In-Command of NORAD is a Canadian (it's NORTH AMERICAN Air Defence, not American Air Defence) - and yet in all the movies set in Cheyenne Mountain there is nary a Canuck in sight.
** Also, Cheyenne Mountain is in ''[[Stargate SG-1]]'' and ''[[Jeremiah (TV series)|Jeremiah]]'' (This one has the benefit of being a real complex). In the original movie ''[[Stargate (film)|Stargate]]'', the Gate was hidden in the fictional Creek Mountain complex—also in Colorado, and to boot having recycled the Cheyenne Mountain entrance set from ''[[War GamesWarGames]]''. The series retconned the Stargate's location without much fuss.
** Raven Rock, most famous to gamers from ''Fallout3'', is a real base built for much the same purpose as Cheyenne Mountain.
** Offutt Air Force Base is rumored to have an underground command center proof against anything short of a direct hit with a nuke. It's impossible to be certain, because those chambers are ''not'' on the Official Elementary School Field Trip tour, they're still in use. ([[George W. Bush]] did not fly to Omaha on 9/11 because he wanted steak for lunch ....)
** After the Cold War, the Strategic Air Command bunker in Amherst, Massachusetts was put up for sale. Who besides the government could want an elaborate concrete bunker? Librarians, apparently; the Five Colleges bought it for cheap, and now use it for book storage. The low temperatures and lack of sunlight are ideal for preservation, and it's hard to beat the security.
** Speaking of decommissioned bunkers and missile silos, there's a [{{{http|://www.missilebases.com/ real estate company}}] specialising in such properties.
* After the First World War, the French built the [[Maginot Line]] on their border with Germany, a chain of defensive fortifications connected by underground tunnels with bunkers and living facilities. It was an amazing feat of construction. And ever after, people have caricatured it by pointing out that the Germans went around it—which is [[Maginot Line|true but misleading]], because that was the ''purpose'' of the Maginot Line.
* Toward the final years of [[World War 2]] Japanese took to building these to escape the intense naval and air firepower. The result was that some of the nastiest island battles(sieges might be a more accurate description) centered on rooting Japanese out of caves. Generally they would fight on, even when communications were cut, to near annihilation.
* For contrast, Britain had Kelvedon Hatch Nuclear Bunker, a base for the nation's power structure hidden beneath a nondescript house. Apparently, it was active until 1992 (but only ever activated once: not for a nuclear crisis but for the poll tax riots). [https://web.archive.org/web/20130616133436/http://www.muddyclay.com/october.htm This site] has pictures of it. It's now a tourist attraction and the real command centre is somewhere secret.
** Has been used as a filming location.
*** Tourist signs directing people to it clearly say "[http://russelldavies.typepad.com/planning/images/secret_nuclear_bunker-thumb.jpg Secret Nuclear Bunker]".

** [[Conspiracy Theorist]]s [[Epileptic Trees|speculate]] about the existence of DUMB, or Deep Underground Military Base. It doesn't sound any more sinister than your regular well-protected military base, except that it's supposedly run by your favorite conspiracy ([[The Illuminati]] and [[The Reptilians]] being popular choice) and people are abducted and carried there for unspeakable purposes.
* Željava Air Base in former Yugoslavia is the world's largest underground ''Air Base''. While they still have overground runways, everything else is underground and has enough food, fuel and ammo to survive 30 days without outside intervention. It has been, alas, demolished.

* The North Korean military has a lot of bases created underground, some hollowed out from mountains to protect their equipment from bombardment in a future conflict involving South Korean and American bombing raids. The North Korean military also had several underground tunnels built so their troops could surprise-invade South Korea when the time is right.
* Muammar Gaddafi, the former dictator of Libya, had a huge underground base hidden under Tripoli. Among other things, it contained an entire functioning hospital and stockpiles of food large enough for an entire city. It also had tunnels big enough to drive tanks through.
